An An, born in the 1990s, is a troubled girl. Because her parents were very busy at work and neglected An An, An An became a rebellious and troubled girl. In order to make An An feel "comfortable", her parents sent An An to Lebia High School, which has a strict teaching system in City C. An An, on the other hand, makes trouble everywhere and racks her brains to get her expelled from the school. An An meets Han Muxuan, who is number one in appearance and grades. What kind of sparks will they create? When An An was preparing to celebrate Han Muxuan's nineteenth birthday, an old man found An An. Unbelievably, this old man turned out to be Xiahou Mo, one of the top ten richest men in Asia. What's even more incredible is that this old man said that An An is his granddaughter. What's going on? Where should An An and Han Muxuan go?
